NEX JERSEY, A CORPORATION OF SHOE-SUPPORT.

Specification of Letters Patent.

Patented Dec. 28, 1915 Application filed April 13, 1910. Serial No.555,294.

To all whom it may concern Be it known that I, THOMAS G. PLANT, acitizen of the United States, residing at Boston, in the county ofSuffolk and State of ll lassachusetts, have invented an Improvement inShoe-Supports, of which the following description, in connection withthe accompanying drawings, is a specification, like letters on thedrawings representing like parts.

i The invention to be hereinafter described relates to shoe supports,and more particularly to such supports for sustaining a shoe in positionwhile the heel is being treated, although, as will be understood bythose skilled in the art, it may be employed for other purposes.

The aims and purposes of the present invention are to provide a shoesupport of the general type mentioned, which shall be simple inconstruction and efficient in properly sustaining the shoe in positionfor treatment, all of which, and other objects, will best be made clearfrom the following description and accompanying drawings of one form orembodiment of means for carrying the invention into practical effect, itbeing understood that the invention is not circumscribed by theillustrated details, but is defined in its true scope by the claims.

An illustrated use of the present invention in connection with anorganized machine is afforded by Patent No. 1,107,838, Aug.'18, 1914-,for heel breasting machines, and to this patent reference may be had fordetail description of means, such as heel breasting means, for acting onthe heel of a shoe sustained by the shoe support which forms the subjectof the present application.

In the drawings :-Figure 1 is a front elevation with part of the framebroken away, showing sufficient of a machine for treating shoes to makeclear the construction and operation of the present invention; Fig. 2 isa side elevation of the parts shown by Fig. 1; Fig. 3 is a section onthe line 3-3 of Fig. 2; Fig. 4 is an enlarged detail view, showing theupper portion of a shoe support and its adjusting means; Fig. 5 is asection on the line 5-5 of Fig. 4; and Fig. 6 is a section on the line66 of Fig. 4,. r

The machine frame for su orting the operating parts of the machine maybe of any usu l or desire ha acter, and herein rep resented as a column1 having suitable upwardly extending portions 2, Figs. 1 and 2, forsustaining and guiding the moving parts.

These features may be any form and kind suitable to the purposesintended, as pointed .out in said prior application.

Mounted in hearings in the lower portion of the column 1 is the mainshaft 5, Figs. 1 and 2, provided with suitable driving means, as thepulleys 6 and 7, both of which may be loose on the shaft, so that whenthe belt is shifted to the pulley 6, said pulley may run idly withoutdanger of starting the machine even though the machine starting means beoperated. The pulley 7,however, as pointed out in said priorapplication, while loose upon the driving shaft 5, may be connectedthereto at desired times to cause one rotation of said shaft, whereuponthe shaft may come to rest, all as more fully explained in said priorapplication, and which, forming no part of the present invention, is notfurther herein described.

Pivotally mounted at 8 on suitable sustaining lugs 9 at the base of thecolumn 1 is a swinging jack standard or support 10. The swinging jackstandard or support 10 projects upwardly and passes through a suitableaperture in the sliding plate 11 which is mounted in suitable guidewaysin the table 12. The table 12, it will be noted, has an inclined upperface, and so also has the sliding plate 11, the purpose being to causeany chips or scraps that may drop from the shoe during the operation ofthe machine to pass therefrom and not lodge thereon to the detriment ofthe working parts. It will be noted that the table 12 and the slidingplate 11 extend for a considerable distance from front to rear of themachine and that the sliding plate practically covers the guide openingin the table 12 when the swinging jack standard or support 10 is eitherinits front or rear position, as

will presently appear.

secured beneath the table 12 is a yielding bunter or stop 13, Fig. 2,which is adapted to be engaged by a projection or part 14 connected tothe sliding plate 11, the construction being such that when theswinging.

jack standard or support 10 is moved from its front to its rear positionabout its pivotal support 8, the part 14 will contact with the yieldingbanter 1,3. and bring the part grad the end portion 27 a, if the handle26 beforceddownwardand ,5 i t -.th ig t. h segm ually to rest, insubstantially correct position for the operation of the heel breastingor other means.

The upper portion of the swinging jack standard or support 10, see Figs.4 and 5, is provided with a recess in which is sustained the jack post16, the lower end portion of which rests upon a wedge 17. In the presentform or" the invention the wedge l7 is preferably formed as a segmentand is guided in theswinging jack standard by means-ofa groove 18 which,in cooperation with theside openings in the standard through which thesegment wedge passes, atford convenient meansfor holding the segmentwedge in proper jack post sustaining position. The lower end portion oi.the jack post 16 maybe provided with a groove, as 19,"Fig. 5, to engageabout the upper surface of the segment wedge as a convenient means formaintaining the parts in coacting relation. The segment wedge l? ismounted to swing about-a center on the swinging jack standard, theconstruction being such that "as the wedge is swung relative to the jackstandard and jack post, the latter will be raised or lowered toaccommodate the conditions of work, as will be readily understood bythose skilled in the art.

means for mounting the segment wedge 17, the swinging jack standard isprovided witha lug 20 which sustains a pin 21 which itself affords apivotal support for the arms22 and 23, the other ends of said arms beingappropriately connected at 2st and 25 to the segment wedge, as willbereadily understood from Fig. 4. As a preferred construction the arms 22-and 23 are duplicated, one set being at each side of the swinging Tjackstandard, as indicated in Fig. 55, whereby a steady and eliicientswinging support is afforded for the segment wedge 17. Inorder that thewedge 17 may be conveniently and readily moved about its center 21 toproperly position the jack post and consequently the work, a handle 26is provided, said handle being pivoted at 24 to the segment Wedge 17and, to maintain said handl'ein appropriate position for the operator,below the connection 24 is pivotally connected at 28 to a link 29, the

opposite end of which is pivoted at 30 to the lug 20, the constructionbeing such that as the handle 26is pushed or pulled, asthe case may be,to ad ust the swinging segment wedge 17 to appropriate or desiredposition,

the link 29 will serve to maintain the handle hand of the regardless ofwhether the wedge as will be clearly For instance, the indicated in Fig.

operator,

understood from Fig. 4t.

wedge will be moved endwise to the right, and as it thus moves, the link29 acting on the end 27 of the handle 26 will so alter the path ofmovement of the handle 26 as compared with that of the segment wedge 17that said handle will be maintained in convenient position for the handof the operator, as will be readily understood.

The shoe support and jack of the present invention is more especiallydesigned to support a shoe while on the wooden last for treatment by theheel breasting or other devices, and to this end the jack post isprovided with a head block 31, Figs. 4- and (5, which is itself providedwith a curved slideway adapted to engage a coacting or complementalguideway in a pin block 8i, from which projects a last pin 35, theconstruction being such that as the pin block is moved on the headblock, it will be appropriately turned in a vertical plane in accordancewith the angle desired to be given to the heel breast by the breastingdevices.

The pin block i is provided with a recess 57 extending longitudinallythereof in which is loosely contained a spring 58, the ends of which areadapted to engage the slotted end walls 59 of the pin block. Extendingupward from the head block 31 are the end pieces which are also adaptedto engage the ends of the spring 58, the construction being such thatwhen the pin block 3% is moved in either direction as prescribed in theguideways 32 and 83, the spring 58 will be compressed between theapproaching wall 59 of the pin block and the end piece 60 on theopposite end of the head block 31. Thus it will be seen that while thespring .58 normally holds the pin block in position, as indicated inFig. i, it will permit the pin block to move yieldingly in eitherdirection to properly position the heel, such movement being etfected bythe hands of the operator.

As well understood by those skilled in the art, the pin holes of lastsare not always accurately positioned with respect to the last, or arenot always accurately formed so that it becomes necessary at times tomove the jack post to one side or the other in order to bring the heelof the shoe in proper positionfor treatment. In the present form of theinvention this characteristic movement 01 the jack post is provided byforming the jack post 18 with play in the standard, as indicated inFigs. 4: and 5, and providing springs 36 between the jack post and theinterior wall of the swinging jack standard, as indicated in Fig. 5. Asa convenient means of thus yieldingly maintaining the jack post inposition and yet permitting it to be moved sidewi'se to properlyposition the shoe supported by the jack, said jack post is provided withsockets 37 in which the springs 36 are seated, so that such jack postside .or the as lndicated in Lit Fig. 5, the construction being suchthat while the post 16 rests upon or is supported by the wedge 17, itmay be tilted to one side or the other to properly position the shoe,even though the last pinsocket of the last may not be true or central ofthe last, there being sufficient play or looseness between the jack postand wedge, and the ack post and walls of the recess 15 to permit suchtilting movement of the jack post on the wedge and in said recess, aswill be clearly apparent to one skilled in the art. As a means forpreventing turning movement of the jack post while still permitting suchsidewise adjustment, the surfaces of said jack post at 38 are flattenedsomewhat and are engaged by blocks 39 on the interior of the swingingjack standard 10, the construction being such that the blocks 39 whichmay be held in place or adjusted by means of set screws 1-0, Fig. 4;,while preventing rotative movement of the jack post on its vertical axiswill yet permit sidewise movement of the jack post for the purposeshereinbefore noted.

W hen the shoe support and jack have been moved to their operativeposition for the action of the heel breasting or other means upon theshoe. it is desirable that the parts be locked so that the shoe may bepositively held during the action of such breasting or other devices. Tothis end the main shaft 5 is provided with a cam l1 which is engaged bya roll 42 on the arm 43' of the lever which is pivoted at 1-1, the otherarm 45 of which is connected at 46, Fig. 1, to a rod or actuator 47, theupper end of which is con nected to an arm 48 secured to a rock shaft19, substantially as pointed out in the application hereinbeforementioned. Secured to the rock shaft 49 is a toe 50 which supports thearm 51 loosely mounted on the rock shaft 49 by means of a set screw 52which passes through a lug carried by the arm 51, the con structionbeing such that wh an the shaft 49 is turned contra-clockwise, Fig. 1,the toe 50 will. be lowered and the arm 51 will be allowed to descend,substantially as pointed out in said prior application.

Secured to the arm 51 is a rod 53. the lower end portion of whichcarries a lock 54: which may be substantially as set forth in. saidapplication, or otherwise. Projecting rearwardly from the swinging jackstandard 10 is a bracket 55, the upper rear portion of which is providedwith a series of teeth which are adapted to be engaged by the lower endof the lock 54 and hold the swinging jack standard or support 10 in rearposition, substantially as pointed out in said application.

From the construction hereinbefore described it will be apparent thatthe swinging jack standard may be moved to and from operatlve positionand be locked in operative position by means controlled from the mainshaft, and that the jack post carried by the swinging jack standard maybe conveniently and readily raised or lowered by means of the wedge soas to properly position the shoe for the action of the breastingor otherdevices. the handle for thus moving the wedge being appropriatelymaintained in convenient position for manipulation by the operator. andthe wedge itself being preferably swung about a center carried bv theswin9: Eng standard or support. It will also be noted that the jackpost, independent of the swinging ack standard, may be moved sid wiserelative thereto to properly compensate for any inaccuracy in the lastpin socket of the last.
